px5g: creates certificates that expire in the past
the attached patch fixes a bug of px5g when instructed to build
certificates that expire after 2038-01-19, caused a multiplication that
may overflow the "to" variable of type time_t
Attached patch checks if "to" precedes "from": if so sets "to" to its
maximum value. Pretty rude, but works well even if certificate is set to
expire in a century
